Sure, we all love to hear our favorite artists sing the Christmas standards. But the real Christmas miracles occur when pop stars decide to take on the daunting task of recording a holiday original -- and it doesn't ruin Christmas. We've got a playlist full of just those tunes, from the newly composed tunes that have become classics (Merry Christmas, Mariah! Happy holidays, Wham! Feliz Navidad, Waitresses!) to not-quite-classic original holiday jams that have still managed to get our jingle bells shaking. Who needs tradition? Have yourself a (brand spankin' new) merry little Christmas!
